Abstract:
Objective: To investigate the expression of HSP-27,-60 and -90 in gastric cancer and its clinical significance. Methods:66 cases of gastric carcinoma was detected by immunohistochemistry HSP-27,60 and 90 of the expression and clinical significance of combined with clinical and pathological characteristics, tumor cell proliferation and survival analysis of three kinds of heat shock protein expression. Results: HSP-27,-60 and -90 were highly expressed in gastric cancer tissues. HSP-27 expression and tumor size (pT,P=0. 026),organ metastasis (pM,P=0. 046) and pathological staging (P=0. 041),HSP-27 staining intensity and lymph node status were significantly correlated ( pN, P=0. 042 ) . HSP-60 expression was associated with gender ( P=0. 011),and HSP-60 staining intensity was associated with age (P=0. 027) and tumor grade (P=0. 031). There was no correlation between HSP-90 expression and the clinical pathological parameters of this study; however, the intensity of HSP-90 staining was significantly correlated with tumor size (P=0. 020,pT). Single factor analysis showed that HSP-90 was significantly associated with longer survival (P=0. 033). Multivariate analysis demonstrated that HSP-90 was highly expressed as an independent prognostic factor for gastric cancer (P=0. 026). Conclusion: the HSP-27,-60 and -90 and some clinical pathological parameters. These parameters is very important for the treatment of patients with gastric cancer. The high expression of HSP-90 in patients with gastric cancer were inde-pendent prognostic indicators.
